Got a a6 c7 2.0 tdi
Alarm started going off and went to unlock car with key and nothing happened ended up using key blade , to.find non of other doors unlocked so tried to put ignition on didnt work , so basically its like its flat battery.
So non of the other doors will unlock , ignition wont turn on , steering lock on , parking brake wont release , nothing is working on car like power lost to everyrhing
Iv had the battery tested bt was replaced couple of months back so battery is decent, checked all fuses inside car in boot , dashboard either sides and under the bonnet all good non faulty

Stereo an popup screen work also parkimg brake warning light on dashboard

Changed batterys in key still no different, aa came out and checked over car came back with communication error for faults above

It looks like energy management is active - this will disable modules one by one. Energy management is activated when the system detects a flat/failing battery.
When the battery was replaced, was it coded to the car? If not, the system will keep on charging the new battery at the old battery rate causing another flat battery.
